I just don’t get it!
I think it is a good comment for a 6th, 7th, even 8th grader, maybe from a college student one might ask a little bit more, but the disturbing things are the ironical and sometimes plainly offending handwritten comments.
Though I don’t think they are from a teacher because the writing style seems not to be very skilled in that sense that this person doesn’t seem to be used to write often by hand as teachers normally do (all those corrections in tests…) and a teach don’t draw pics like the AstronomySuperHero…
